Gas Work- 7 May 2019
Jason was a breath of fresh air. He is highly professional, totally ethical and has great integrity. Unlike many engineers who took no time in quoting me for a brand new boiler,Jason checked the boiler to accurately ascertain what precisely was wrong with it in order to determine whether a new boiler was necessary at all. He identified the problem to an external loose valve above the boiler which was leaking. He kindly tightened the valve and stopped the leak. My sincere thanks to Jason for saving me in excess of £3000.00!

Extensions- 6 Oct 2022
I was lucky enough to have Haroun on this project of side extension and outside building. He is such a professional guy and always committed to do his work up to the standard. He has been very nice to us and always responded whenever asked to do additional jobs. He is very honest and trustworthy and his team has been very wonderful. I'm very happy with work he did in the house and would hire him again should the necessity arise in future.

Handyman- 6 Jan 2026
Firstly, I havent used mybuilder in years, and I hired Zaim hoping for a good job on our dining chairs. I can safely say I was very suprised. He did an excellent job. From the moment we talked he had great communication, he was timely and said he would call 30 mins before arrival which he did, he spent time fixing the legs of the chairs as if he were doing the work in his own home. He is also not afraid of letting you watch him work, he has nothing to hide and is genuinely a nice person. He wants to do a good job and doesn't leave until the room is in the condition it was in before he came, he even hoovered up afterwards. Zaim was professional, calm and knowledgeable. Some people do a rush job, but you could see he wanted to do a job that was good, even redoing work because he wasn't happy with it. A solid job. Would certainly recommend.
